Pool fountain

Abstract

A novel fountain device for a swimming pool is disclosed which features an adjustable jet pump for controlling the elevation of the water column as it is ejected from the fountain and the rise and fall of said column from a minima to a maxima.

I claim: 
     
       1. A fountain for a swimming pool comprising: (a) an extended tubular arm having a quick disconnect flow through valve connectable on one side to an underwater swimming pool water inlet on the first end of said arm,   (b) hollow means for altering the path of fluid flow from generally horizontal to generally vertical connected on one side to the other end of said arm,   (c) an orientable flow through ball valve disposed between and connected to said hollow means on one end,   (d) a jet pump having at least one aperture, and being connected at one of its two ends to said ball valve, said pump including a rotatable collar to adjustably close the apertures of said pump,   (e) a rigid riser generally vertically disposed and having a first end and a second end; the first end connected to said jet pump's second end, all of said parts communicating to form a conduit for a stream of water.   
     
     
       2. The fountain of claim 1 wherein said riser comprises a plurality of telescoping tubular sections for altering the elongation of said riser. 
     
     
       3. The fountain of claim 1 further including a nozzle secured to the second end of said riser. 
     
     
       4. The fountain of claim 1, wherein the jet pump has a plurality of apertures all of which are adjustably closeable. 
     
     
       5. In combination: a swimming pool   a recirculating filter system for said pool including a water return line through which filtered water is returned to the pool, and   the swimming pool fountain of claim 1, said fountain being operatively connected to said filter system.   
     
     
       6. The fountain of claim 1 wherein the orientable ball valve and the jet pump are a unitary structure. 
     
     
       7. A swimming pool fountain comprising: (a) an extended tubular arm connectable at a first end to a water inlet for a swimming pool,   (b) ballasting means fluidly connected to said arm wherein said ballasting means includes a hollow means therein for altering the path of fluid flow from generally horizontal to generally vertical,   (c) a jet pump having at least one aperture, including means to adjustably close said at least one aperture, said jet pump having two ends and being connected at one of its two ends to said hollow means,   (d) a rigid riser generally vertically disposed having a first end and a second end, the first end of which is to said jet pump's other end.   
     
     
       8. The fountain of claim 7 wherein said riser comprises a plurality of telescoping tubular sections for altering the elongation of the riser. 
     
     
       9. In combination: a swimming pool   a recirculating filter system for said pool including a water return line through which filtered water is returned to the swimming pool, and the swimming pool fountain of claim 7, said fountain being operatively connected to said filter system.
